Answer:

y = -5x + 9

Step-by-step explanation:

Slope-intercept form is the form

y = mx + b

So you need to rearrange the terms to get the y all by itself on the left. On the right, the x term goes first and last the constant (a plain number) see image.

Answer:

  ln(x)/2 -3.810930

Step-by-step explanation:

The relevant rules of logarithms are ...

  ln(ab) = ln(a) +ln(b)

  ln(a^b) = b·ln(a)

  ln(a/b) = ln(a) -ln(b)

  ln(e) = 1

__

Your expression expands to ...

  [tex]\ln\left(\dfrac{4\sqrt{x}}{9e^3}\right) = \ln(4\sqrt{x})-\ln(9e^3)=\ln(4)+\dfrac{1}{2}\ln(x)-(\ln(9)+3\ln(e))\\\\=\dfrac{1}{2}\ln(x)+\ln(4)-\ln(9)-3\\\\\approx\dfrac{\ln(x)}{2}-3.810930[/tex]

Answer:

(2x + 1)(3x - 2)

Step-by-step explanation:

f(x) = 6x² - x - 2

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × - 2 = - 12 and sum = - 1

the factors are + 3 and - 4

use these factors to split the x- term

6x² + 3x - 4x - 2 ( factor the first/second and third/fourth terms )

= 3x(2x + 1) - 2(2x + 1) ← factor out (2x + 1) from each term

= (2x + 1)(3x - 2) , then

f(x) = (2x + 1)(3x - 2) ← in factored form

Let the cost of hamburgers and drinks be x and y

According to the question,

[tex]\sf{ 2x + 4y = 13.00 ...eq( 1 ) }[/tex]

[tex]\sf{ 3x + 7y = 21.00 ...eq(2) }[/tex]

Solving eq( 1 ) we get :-

[tex]\sf{ 2x + 4y = 13 }[/tex]

[tex]\sf{ 2x = 13 - 4y }[/tex]

[tex]\sf{ x = (13 - 4y)/2 ...eq(3)}[/tex]

Subsituting eq(3) in eq( 2 ) :-

[tex]\sf{ 3( 13 - 4y)/2 + 7y = 21 }[/tex]

[tex]\sf{ 39 - 12y/2 + 7y = 21 }[/tex]

[tex]\sf{ 39 - 12y + 14y = 42}[/tex]

[tex]\sf{ 2y = 42 - 39 }[/tex]

[tex]\sf{ 2y = 3 }[/tex]

[tex]\sf{ y = 3/2 }[/tex]

Subsituting value of y in eq(3) :-

[tex]\sf{ x = 13 - 4(3/2)/2}[/tex]

[tex]\sf{ x = 13 - 2(3)/2}[/tex]

[tex]\sf{ x = 13 - 6/2}[/tex]

[tex]\sf{ x = 7/2 }[/tex]

Therefore,

[tex]\sf{ Cost\: of \:8 \:drinks}[/tex]

[tex]\sf{ = 8 * 3/2 }[/tex]

[tex]\sf{ = 4 * 3 }[/tex]

[tex]\sf{ = 12.00 dollars}[/tex]

And

[tex]\sf{ Cost\: of \:9 \:hamburgers }[/tex]

[tex]\sf{ = 9 * 7/2 }[/tex]

[tex]\sf{ = 63/2}[/tex]

[tex]\sf{ = 31.50 dollars}[/tex]

Total cost of the 8 drinks and 9 hamburgers

[tex]\sf{ 12.00 + 31.50}[/tex]

[tex]\sf{\red { = 43.50 \:dollars}}[/tex]

Hence, The total cost paid by you for 8 drinks and 9 hamburgers is $43.50 .

Answer:

200

Step-by-step explanation:

This problem is about linear equations. We assume Joe drive X miles, and the total cost is $Y, then we can get:

Plan I: Y=51.98+0.17X

Plan II: Y=59.98+0.13X

When both plans cost the same, 51.98+0.17X=59.98+0.13X. We will get X = 200

There are different ways to estimate a variable. The sample mean is a point estimate of the population mean for the variable of interest.

A point estimate is known to be the value of a sample statistic that is often applied as one estimate of a specific population parameter.

The sample mean is defined simply as a form of average value seen in a sample. A sample is known to be the little portion of a whole.

Answer:

y = 14

Step-by-step explanation:

If the line is horizontal, it will always have the ssame value of y for all values of x.  Therefore, y = 14.

Answer:

x=4, y=-3, or (4,-3)

Step-by-step explanation:

Hi there!

We are given the following system of equations:
-2x+y=-11

4x+4y=4

And the problem wants us to solve it by substitution

In substitution, we will solve one of the equations for one of the variables to equal an expression containing the other variable, then substitute that expression as the variable it equals into the other equation, solve that equation, then use the value of the solved variable to solve for the first equation we made (the one that is a variable equaling an expression containing the other variable)

It's easier to do this when one of the variables already has a coefficient of 1, as we can just move a couple of terms around without having to multiply or divide anything; for example, in the first equation, -2x+y=-11, y already has a coefficient of 1

So we can just add 2x to both sides, in order to solve the equation for y

-2x+y=-11

+2x      +2x

______________

y=2x-11

Now substitute this expression into the the second equation as y.

So, 4x+4y=4 would become 4x+4(2x-11)=4

Now we need to solve 4x+4(2x-11)=4

Do the distributive property:

4x+8x-44=4

Combine like terms

12x-44=4

Add 44 to both sides

12x=48

x=4

We found the value of x

Now we need to find the value of y
Substitute 4 as x in y=2x-11

y=2(4)-11

Multiply

y=8-11

subtract

y=-3

The answer is x=4, y=-3, or as a point, (4, -3)

A table for a problem like this is easily made using a spreadsheet. Each value is 6 times the previous, and each sum is the new value added to the previous sum. The first value and the first sum are -3.
